Effectiveness of the six-step approach guided online training program to improve knowledge of pneumonia among pediatricians: a pretest-posttest study.

Background: In 2023, China witnessed an earlier and more widespread outbreak of pneumonia (MPP). To address this situation, an online training program was designed to enhance the knowledge of MPP among pediatricians in Shanghai, China.

Methods: An online training program on the diagnosis and treatment of MPP, guided by Kern's six-step approach, was developed by the Shanghai Pediatric Clinical Quality Control Center.

Description of the medical services provided to children in Shanghai: a cross-sectional study of the characteristics and disparities of hospitals of different levels and types.

Background: The development of the pediatric care system is uneven in China. Limited research has been conducted on pediatric care in Shanghai, which is a well-developed region in China, in which the National Children's Medical Centers are located.

Methods: In November 2021, under the commission of the Shanghai Center for Medical Quality Control, a city-wide questionnaire designed to examine the provision of medical services to children in Shanghai in 2020 was conducted at 86 hospitals providing pediatric care.

Direct costs of community-acquired pneumonia for hospitalized children in Shanghai, China from 2018 to 2020: a cross-sectional analysis.

Background: Community-acquired pneumonia (CAP) is an acute respiratory infection with a high clinical and economic burden. Clarifying the burden is important for health policy making. However, there is inadequate data on the economic burden of childhood CAP in China.

Expert Consensus on Clinical Practice of Burn Units in Shanghai During the COVID-19 Epidemic.

In response to coronavirus disease 2019 (COVID-19), the Shanghai Burn Clinical Quality Control Center organized experts to formulate and implement a set of rapid, simple, and effective prevention and control measures, and there have not been any cases of health care professionals or inpatients in burn units suspected or confirmed with COVID-19. This article elaborates on the specific measures in burn units in response to the epidemic, including the implementation of standardized procedures, remote consultations, strengthened follow-up, exchange of experience, and popular science, among others. We share experience from Shanghai to benefit related disciplines in other countries and regions.

Shape-Driven EIT Reconstruction Using Fourier Representations.

Shape-driven approaches have been proposed as an effective strategy for the electrical impedance tomography (EIT) reconstruction problem in recent years. In order to augment the shape-driven approaches, we propose a new method that transforms the shape to be reconstructed as basic primitives directly modeled by using Fourier representations. To allow automatic topological changes between the basic primitives and surrounding objects simultaneously, Boolean operations are employed.

Shape-Driven Difference Electrical Impedance Tomography.

This work proposes a novel shape-driven reconstruction approach for difference electrical impedance tomography (EIT). In the proposed approach, the reconstruction problem is formulated as a shape reconstruction problem and solved via an explicit and geometrical methodology, where the geometry of the embedded inclusions is represented by a shape and topology description function (STDF). To incorporate more geometry and prior information directly into the reconstruction and to provide better flexibility in the solution process, the concept of a moving morphable component (MMC) is applied here implying that MMC is treated as the basic building block of the embedded inclusions.

Shape Reconstruction Using Boolean Operations in Electrical Impedance Tomography.

In this work, we propose a new shape reconstruction framework rooted in the concept of Boolean operations for electrical impedance tomography (EIT). Within the framework, the evolution of inclusion shapes and topologies are simultaneously estimated through an explicit boundary description. For this, we use B-spline curves as basic shape primitives for shape reconstruction and topology optimization.

B-Spline Level Set Method for Shape Reconstruction in Electrical Impedance Tomography.

A B-spline level set (BLS) based method is proposed for shape reconstruction in electrical impedance tomography (EIT). We assume that the conductivity distribution to be reconstructed is piecewise constant, transforming the image reconstruction problem into a shape reconstruction problem. The shape/interface of inclusions is implicitly represented by a level set function (LSF), which is modeled as a continuous parametric function expressed using B-spline functions.

B-Spline-Based Sharp Feature Preserving Shape Reconstruction Approach for Electrical Impedance Tomography.

This paper presents a B-spline-based shape reconstruction approach for electrical impedance tomography (EIT). In the proposed approach, the conductivity distribution to be reconstructed is assumed to be piecewise constant. The geometry of the inclusions is parameterized using B-spline curves, and the EIT forward solver is modified as a set of control points representing the inclusions' boundary to the data on the domain boundary.

[Pulmonary functions in children with segmental Mycoplasma pneumoniae pneumonia].

Objective: To investigate the changes of pulmonary functions in children with segmental Mycoplasma pneumoniae pneumonia (SMPP).

Methods: A total of 55 children with SMPP were recruited into this study. Pulmonary functions were measured at both acute and recovery phases, including FVC, FEV1, FEV1/FVC, PEF, FEF25%, FEF50%, FEF75% and FEF25%-75%.
